My point was not that ceramics usually suck for audio... just... how bad do they
suck.  For interstage coupling of let's say... the noise source in Chris' MiniModular
how would you HEAR if there was any distortion.  It might "color" the sound but you
would probably not notice. Hence the ceramics "might" be ok. As I've said I don't
use 'em for that.

For the caps in a VCF they are no damn good.  Ditto VCO.  But maybe in some
envelope generator apps... like pulse forming, they are fine.

The trick is to use the correct part and learn why you are using that part.

PS.  Hey Magnus, if you use much Teflon you got more money than me !!!
